Celebrating the 40th anniversary of Doctor Who, this release looks back through the radio archives and highlights the wide variety of Doctor Who features and interviews which have been broadcast over the years. Dozens of extracts - many of which have been unheard since their first broadcast - illustrate how the programme has been a national institution, held in fond regard by adults and children alike.

John Barrowman, Eve Myles and Gareth David-Lloyd star in seven full-cast BBC Radio 4 dramas based on the hit BBC TV series. In "Lost Souls" by Joseph Lidster, voices from the past are calling out from the Large Hadron Collider at CERN, and scientists are disappearing. Can Torchwood help? 'Asylum' by Anita Sullivan sees PC Andy Davidson turn to Torchwood after he arrests a very unusual shoplifter. 'Golden Age' by James Goss finds the team in Delhi, on the trail of a dangerous energy field.

According to The Nice and Accurate Prophecies of Agnes Nutter, Witch (the world's only completely accurate book of prophecies, written in 1655, before she exploded), the world will end on a Saturday.

Everything appears to be going according to Divine Plan.
